Title: Radar beacon apparatus
Inventor: MATSUBARA HIDEKAZU
IPC: G01S13/75
Filed: 1982-04-26
Abstract: PURPOSE:To enable the transmission of a pulse signal with a pulse width to match the distance range of a radar carried on a ship or the like by controlling the transmission pulse width according to the level of a signal received. CONSTITUTION:A radar pulse signal from a ship radar is introduced into a detector 3 through an antenna 1 and output thereof is amplified 4 and fed to a trigger generator 5 and a level detector 6. Then, the level detector 6 controls a pulse width setting circuit 7 according to the level of a radar pulse. The pulse width setting circuit 7 sets the pulse width of a transmission pulse signal according to the level of a signal received. When the level of the signal received is high, it controls a pulse driving circuit 8 so as to lessen the pulse width and to enlarge it when it is low. This enables the trnsmission of a pulse signal with a pulse width to match the distance range of a radar.

Title: Burner
Inventor: SAKINO KOJI
IPC: F23C99/00
Filed: 1986-03-27
Abstract: PURPOSE:To provide a burner which is capable of reducing formation of NOx by forming a first gas jetting-out opening on the bottom face of a recessed section in the upper center of a burner main body and a second gas jet-out opening on the outer periphery of the burner main body and making the combustion of gasified kerosene that has been premixed with the primary air at the first gas jetting-out opening and the combustion of gasified kerosene that has been diluted by diluted air from side face holes on the whole circumference of a burner cap coexist. CONSTITUTION:Ignition is made by fuel gas that jets out from a first as jetting-out opening 5 on the upper face of a recessed section and is not diluted, and with this burning flame a fuel gas that jets out of a second gas jetting-out opening 6 and is diluted by a primary air C from an air intake opening 9 contacts and the fuel gas burns. The form of the combustion is such that the combustion of gasified kerosene which is premixed with a primary air at the first gas jetting-out opening 5 and the combustion of gasified kerosene which is premixed in the inside of a burner main body 2 with this primary air and which is further diluted by diluting air from the side face holes on the whole circumference of a burner cap 8 coexist. Since the combustion from the second gas jetting-out opening 6 has a high air ratio and burns in the center of the flame by a mixture with low concentration air that is left in the exhaust gas in the combustion from the second gas jetting-out opening 6, formation of NOx is suppressed.

The intermediate intensity light has the nearly intermediate intensity between the non-attenuated intensity of the light passing a reticle substrate layer and the intensity of the completely attenuated light shut off by the opaque layer of the reticle. The exposed photoresist receives the light of two sets of the intensity, by which via holes are formed in the resist in response with the light of the higher intensity.  The connection lines to the via are formed at the intermediate level of the photoresist in response with the intermediate light intensity. The method for forming the multilevel resist from the multilevel reticle and the multilevel reticle device are provided.

The outdoor hood body 1 is buried in the wall 5 and fixed with cement mortar, etc., and a duct 4 piped from indoor is connected to the duct connector 2. Although the opening 3 alone is seen from outdoor, the intrusion of rain water into the duct 4 can be prevented because the duct connector 2 is positioned in the upper part even when rain water goes into the opening 3. The rain water flows out from the opening 3 and the intrusion of noise can also be prevented.

Title: Image pickup controller
Inventor: OONUMA TAKASHI
IPC: H04N5/238
Filed: 1981-05-11
Abstract: PURPOSE:To avoid a hunting phenomenon and at the same time to realize a forcible closing operation, by preventing the full stop-down operation by detecting the aperture value optained immediately before the aperature is fully stopped down. CONSTITUTION:The video signal is turned into an auto iris signal through an auto iris signal detecting circuit 1 and supplied to an auto iris amplifying circuit 3. The circuit 3 detects the aperture value obtained immediately before the full stopping-down from an iris follow potential meter 7 and produces the signal which controls an internal voltage limiting circuit. As a result, the voltage of the auto iris signal is limited, and the stop-down operation is prevented to avoid a hunting phenomenon. At the same time, the voltage limint circuit becomes inactive with an input of the forcible close signal. Thus the aperture can be fully stopped down. In such a way, the hunting phenomenon can be pevented and at the same time the forcible closing operation is possible.

Title: Supersonic-speed wind tunnel
Inventor: SAKAI HARUO
IPC: G01M9/00
Filed: 1984-04-09
Abstract: PURPOSE:To reduce the using pressure of each piece of equipment, by varying the restriction of the second throat in supersonic-speed wind tunnel, which discharges the compressed air that is stored in an air storage tank into an atmosphere through a valve, a collecting tube, a nozzle, a measuring tube, the second throat and a diffusing tube. CONSTITUTION:An air exhausting device 10 in supersonic-speed wind tunnel is operated, and the pressure in a measuring tube S is made to be an atmospheric pressure of 0.6kg/cm<2> ABS. By opening a regulating valve 4 quickly, a gas, which is stored in an air storage tank 3 at the pressure of about 10kg/cm<2> G, is sent to the measuring tube S through a collecting tube 5. Under this state, the pressure in the measuring tube S is reduced by the air exhausting device 10. A shock wave is pushed toward the downstream of a second throat 7 readily by the low pressure of about 5kg/cm<2> G in the collecting tube 5. The wind speed of Mach 4 is obtained in the measuring tube S. Then a jack 9 is operated, the second throat 7 is restricted and the air exhausting device 10 is stopped. Even though the second throat 7 is restricted and the air exhausting device 10 is stopped, the shock wave does not enter the measuring tube S.

Abstract: PURPOSE:To prevent stacked form from being collapsed easily and accurately by a method wherein the pressure-sensitive adhesive tapes having a specific adhesive force are applied to stacked corrugated-cardboard cases extending over at least the two cases. CONSTITUTION:A pressure-sensitive adhesive tape 2 consists of a sheet of kraft paper 21, a polyethylene laminate layer 22 formed on the rear side thereof and a pressure-sensitive adhesive layer 23 formed on the surface thereof and the tapes 2 are adhesively wound around corrugated cardboard cases 1. The pressure-sensitive adhesive tape 2 having an adhesive force of 50-200g/25mm is used. Due to the adhesive force of at least 50g/25mm width, the tape will not be separated from the stacked corrugated cardboard cases secured together adhesively by such tapes during storage and transit. When the tapes are removed from the cases for unstacking, skin papers will not be peeled off from the surfaces of the cases, since the adhesive force is at most 200g/25mm width.
